Engine Performance problem
1998 Ford Contour 4 cyl Front Wheel Drive Manual 69000 miles
CAR DIED WHILE DRIVING. HAD NEW FUEL PUMP INSTALLED. WAS TOLD IT NEEDED CAT. HAD THAT DONE ALSO. NOW CAR WILL ONLY START AND RUN IN SHORT SPIRTS AND HAS STRONG FUEL SMELL AND SMOKE COMING OUT OF TAILPIPE?
What color smoke? Black=too much gas, white= head or head gasket, blue= oil. Check your oil dipstick, you may find gas in the oil from cranking the engine without it starting, a new oil filter and fresh oil is needed, also was the fuel pressure tested after the fuel pump was installed? You may need a new fuel pressure regulator. Or the return line is blocked.
Fuel pump pressure is 30-45psi with key on engine off. Fuel pressure and regulator test:
FUEL PRESSURE 1. Visually inspect fuel system, including fuel lines, connections, injectors and electrical connections. Ensure Inertia Fuel Shutoff (IFS) switch is not tripped. Check condition of battery and fuses. Ensure fuel level in tank is sufficient. 2. Turn ignition off. Release fuel pressure. Install fuel pressure gauge. Start engine and increase engine speed to 2500 RPM. If engine will not start, cycle ignition switch several times. Measure and record fuel pressure. For fuel pressure specifications, see FUEL PRESSURE SPECIFICATIONS article. If fuel pressure is within specification, go to next step. If fuel pressure is not within specification, go to CIRCUIT TEST HC in TESTS W/CODES - 2.0L article for fuel system diagnosis. 3. With fuel pressure gauge still installed, cycle ignition switch on and off several times. Record fuel pressure. If fuel pressure is at least 25 psi (172 kPa) after one minute with ignition off, system is capable of maintaining fuel pressure. If fuel pressure is not at least 25 psi after one minute with ignition off, check for leaking fuel injectors or fuel pressure regulator. WARNING: ALWAYS relieve fuel pressure before disconnecting any fuel injection-related component. DO NOT allow fuel to contact engine or electrical components.
